AI Analysis

Impact

The vulnerability resides in the replication component of Oracle MySQL Server and MySQL Cluster. An attacker with high privileged access to the host where MySQL is running can trigger a hang or a repeatable crash, resulting in a denial of service for the database. The flaw does not expose data or alter configurations, but it completely disrupts database availability.

Affected Systems

Oracle Corporation MySQL Server versions 8.4.0 through 8.4.10 and 9.7.0 through 9.7.1, as well as MySQL Cluster versions 8.0.0 to 8.0.47, 8.4.0 to 8.4.10 and 9.7.0 to 9.7.1 are impacted.

Risk and Exploitability

The CVSS v3.1 base score for this vulnerability is 4.1, indicating that its impact is limited to availability with no confidentiality or integrity compromise. The EPSS score of less than 1% signifies a very low probability that this weakness will be actively exploited in the wild. This flaw is not included in the CISA KEV catalog. Exploitation requires a local attacker who already has high privileged access on the machine hosting MySQL and can interact with the replication component; from there the attacker can trigger a hang or repeatable crash, causing a denial of service for the database.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Review and apply the latest Oracle MySQL Server or MySQL Cluster security updates that address the replication component.
  • Enforce strict least‑privilege policies on the host running MySQL, ensuring that only trusted administrators can execute processes with elevated rights.
  • Monitor the replication channels for abnormal termination or repeated crashes, and consider implementing resource limits or fail‑over mechanisms to mitigate service disruption.
